Before beginning these procedures, you should ensure that the map displayed on the Navigation window is at an extent that allows you to capture the coordinates. Geographic coordinates that are drawn on the map will use the coordinate system and format that is specified in the Point and Polygon/Polyline List window even if the map is projected to another coordinate system and/or format.

To specify point and polygon coordinates by drawing on the map:

1. Click the button.
   
2. The draw-on map toolbar displays on the IMSMA Navigation window.

3. Select the type of shape for which you are specifying geospatial information from the Shape list.
4. Select the type of point that you are specifying from the Point Type list.
5. If you need to manipulate the map on the IMSMA Navigation window before you can capture the coordinates, change the map extent as needed.

   You may need to click the button in the toolbar of the IMSMA Navigation window after using the map controls.

6. Click the point(s) on the map for which you would like to capture the coordinates.

   If you click on the same point more than once, no distance and bearing between the points with identical coordinates will be displayed in the Polygons table.

7. Repeat steps 3–6 for each point, polygon, or polyline that you would like to enter into the Data Entry Form.
8. Do one of the following:
   • If you would like to save the geospatial data, click the button. The draw-on map toolbar closes and the coordinates of the selected points are listed in the Points window or Polygon and Polyline Points window.

   To preview the points or polygon that you entered, click the button.

   • If you would like to exit the draw-on map toolbar without saving any changes, click the button.
